The benefits and uses of refrigeration and portable freezing rooms

Suitable Sizes of Wheeled Mobile Cold Storage (the portable cold storage shown in the picture)

The unit in the picture is an all-in-one factory-assembled mobile cold storage with universal casters at the bottom, which is extremely popular in the African market. Its temperature ranges from -18℃ to +20℃, compatible with fruits, vegetables, meat and fish. Widely applied on farms, in markets and small processing plants, it supports switching between refrigeration and freezing modes.

Three mainstream size options (internal clear dimensions, with volume as the key reference):

For small farms and small vendors (top-selling export model, similar in size to the unit in the picture)

Internal dimensions: 2.4m × 1.8m × 2.0m ≈ 8.6 cubic meters

Approximate external dimensions: 2.8m × 2.2m × 2.3m

Storage capacity: 2–3 tons of fruits and vegetables, or 1.5–2 tons of meat

Advantages: Fits into a 20-foot shipping container for export; equipped with 4 heavy-duty universal casters, movable by 2 to 3 workers; operates on single-phase 220V power supply, perfectly suited for rural African areas lacking three-phase electricity.

This is the standard model receiving the most inquiries from overseas clients.

For medium-sized farms and markets (second highest sales volume)

Internal dimensions: 3.0m × 2.0m × 2.0m ≈ 12 cubic meters

Approximate external dimensions: 3.4m × 2.4m × 2.3m

Storage capacity: 4 tons of fruits and vegetables, or 2.5–3 tons of meat

Ideal for farmers with stable output. Drawbacks: Bulky, occupying much shipping space; some units require a forklift for relocation.

Mini compact model (for family-run small farms and tiny retail stores)

Internal dimensions: 1.8m × 1.5m × 1.8m ≈ 4.8 cubic meters

External dimensions: 2.2m × 1.9m × 2.1m

Storage capacity: 1–1.5 tons of fruits and vegetables

Features low price and flexible mobility, yet limited storage capacity.

Container-style mobile cold storage (another category without casters, transported by trailers)

10-foot container cold storage: internal dimensions approx. 2.9m × 2.3m × 2.3m

20-foot container cold storage: internal dimensions approx. 5.7m × 2.3m × 2.3m. Suitable for large-batch storage with low unit costs, yet cannot be moved manually and requires a trailer or forklift.

Key Selection Tips for African Overseas Projects

Prioritize internal net volume instead of only external dimensions. The insulation panels are 100–120mm thick, leading to larger overall external measurements.

If manual movement is required, a single unit is recommended not to exceed 12 cubic meters, as heavier units cannot be pushed by manpower. For red clay dirt ground, heavy-duty rubber casters are mandatory.

Power supply: Models of 8–12 cubic meters are preferentially designed for single-phase 220V power. Most regions in Africa lack 380V industrial electricity, and the units can work with generators.

Temperature settings: 0~+8℃ for fresh-keeping fruits and vegetables; -18℃ for frozen meat. The unit must support dual-temperature switching, consistent with the specifications of the model in the picture.

Brief Summary & Recommendations

For export businesses targeting the best-selling African model pictured above, the 8-cubic-meter version (internal size 2.4m × 1.8m × 2.0m) is the top recommendation. It balances storage load capacity, shipping container compatibility and manual movability, enjoying the highest market acceptance.
